ltt is an object of the present invention toprovide a device of the character sh in Which feeding; mechanism Will (term part oi? the machine, the said teedinc; me 2hanisnrbeinp; actuated in an improved and positive manner to insure the achievement otthe result desired. U

It is a further object of this invention to provide a ci'itting element operating in con nection with the feeding; mechanism which cutting; element willhave. a etrippinn much-f anisni associatedwith it. whereby any ten-- dency of the material being cut. clinch the knit'e Will be avoided.

ll ty invention turther contemplates the provision of a structure by means oi? Which the tteedino; mechanism will be cleansed otter each mierotion, thereliav insuri a sta (la d oi sanitation Which will be above th t achieved by machines of a simiiar type.

As has been shown in these various lip;- ores the reference numeral 10 indicates a table or platform which may be suitably supported by a frame 1.], it being"; notedin this connection that an opening is provided extending; centrally oi the table, Which a sectional plan view taken open: is :t'orineo with rail portions 12 adacent its edges for a purpose hereinafter specified.

tiny suitable tvpe oi? conveyor be uti lived to effect a teedinc; ot the substance alone: the table. but in the embodiment illustrated it will be seen that l have provided sprocket wheels adjacent'each end of the opening; ot' the table, and an endless sprocket chain let extends around these WlIBtFlS so that when the latter are rotated the chain Will he bodily moved. Affined to certain links of the chain are platt'ornis 15 which. in aggregate when arranged in a common plane provide a. continuous 'fi ace, and the rail portions 153 :tormine; a part oi? the table serve as rests tor these platforms, as Well as guides for the same. so that continuous even moving su .ce fills the opening torma part of the table. will thus be obvious assumii w that suitable mechanism is urovided to n ve the chain, that the conveyor thus termed will be moved continuously along the table and thus any substance placed upon til) conveyor will also be moved along the table. ltn view of the fact that the machine is p rticularlv intended tor the handling}; of ice crea A and similar substances. l. nth); o rippiu or contact shoes '16 one to each of the pla terms 15. and thus it will be obvious that irrespective oi? the operations which the material .1redone-cost. in its pass alone the table, these operations wit not effect a movement of the material or substance with respect to the platform.

New with a view at providing mechanism which will serve to positively more the conveyor, attention. is primarily invited to Figures. 2 and 3. it will be seen. in thee views that one of the sprocket Wheels is mounted upon a shait 17 to which a ratchet 5--5 and in the direction. ct

18 is attached, itbeing also noted that a beam 19 is mounted upon this shaft in such. a manner that it is capable of being oscillated. A main operating shaft 20 is can ried by the frame 11 and mounts ec-rsenti cs 21, one'of which may carry a roller 22, and alever 23 carries near one of its ends a rigidifying enlargement 25 adapted at intervals to be engaged by a roller 22 and. lifted abOve shaft 20 against the action of a spring 24-. The opposite end of this lever 23 is connected to the beam 19 by means of a link 25. A movable fulcrum for the lever 23 is provided by rockingly securing the same to a traveler'26 which may be posi tively moved any suitable means such as a screw threaded shaft 27 conveniently operated by a hand crank 28. The parts just described permit careful adjustment of the lever 28 in setting up the machine.

Thus it will be appreciated that the rotation of the shaft 20 will result in the eccentric 21 also being rotated, and incident to the fact that the lever 23 is urged toward the roller 22 by means of the spring 24 it will be obvious that the said lever will be intermittently rocked. This motion will be transmitted to the link 25 and in turn to the beam 19, and due to the fact that the beam carries a pawl 29 which is in engagement with the ratchet 18 it will be seen that the rocking of the lever will be translated into rotation on the part of the shaft 17. No spring of the common leaf or coil wire type is shown in connection with the pawl 29, although, of course, the use of such spring may be made. I prefer to design the pawl as indicated so that the same is suitably proportioned and disposed to locate its mam weight-masses above its point of pivoting and lying to one side of such point and in toward the ratchet.

After the substance to be out has been moved by the conveyor to the end of the table it may be moved to a delivery platform by any suitable means such as a chute 30, which will deliver the substance to a second conveyor 21 associated with the delivery table 32. However to cleanse the platform of the first named conveyor after it has effected its delivery it will be seen, reference being had to Figure that a trough 83 extends below the opening within the table 11 and the platforms upon their return passage to the forward end of the table, pass between two perforated pipes an, which latter straddle the conveyor and serve to direct jets of fluid against the opposite faces of the platform to accomplish the result desired, the waste fluid flowing from the trough 33 through a suitable drain pipe 35.

The eccentrics 21 in addition to effecting a movement of the conveyor, also serve operate the cutting knife 36, and this latter member is preferably carried by a head 37 slidably carried upon columns 238 secured to the table. Crank arms 39 have one of their ends attached to the head 37 and their opposite ends terminate in bearings 40 encircling the eccentrics 21. Thus while the lever 23 has its link-adjacentend swinging upwardly and lost motion is occurring beween the pawl and ratchet structure, and

the conveyor accordingly remaining stationary, the eccentrics will effect a deprcs sion of the head by means of the crank arms 39, and the knife 36 will be depressed to effect a sei erance of the substance upon the conveyor.

Assuming that ice cream or a similar substance is being cut into blocks by the machine, it will be appreciated that under certain conditions this substance will tend to cling to the l-znife blade upon the latter being retracted by the continued rotation of the eccentrics, and with a view f preventing this occurring, 1 provide stripping meas serving to effect a detachment of the substance from the knife. In the embodiment illustrated this stripping means includes stai'nlards all. which carry spring pressed rods 42 in turn suporting blades These latter elements are arranged in a plane just beyond the plane normally occupied by the upper surface of the substance being cut, which is thus free to more under the inc. Upon this substamte being carried upwardly by the knife, however, it will be obvious that the upper surface f" the same will strip against the under faces of the standards a l arranged to both sides of the knife, and this operation will client a stripping of the substance from the knife, which accomplishes the result (lcsiicd in this connection.

Finally although 1 may utilize a straight knife such as has been shown in l igurcs l to 3, which effects a transverse severance of the substance carried by the c()!1\'c \'ol, I may conveniently employ :1 knife shown in Figures 5 and (l, in those instances where it. is desired to not alone cut the substance transversely, but also longitudinally and edge.- wise. .Vith a view of cll'cctinuall of these cutting operations in the interval required for the knife to accomplsh one depression. it will be seen, reference being bad to the last named figures, that 1 may prinnn'ilv secure a supplemental blade ill to the main blade l5, and due to the fact that this blade extends transversely to the main blade 45, which latter corresponds to the blade 20. it will be obvious that the simultaneous lonq'itudinul and transverse cijitting of the sub stance will be clliectcd. Racks 41') are altached to the head 37 and these racks upon being reciprocated by the head, serve to effect a rotation of gears 47, the teeth of which they engage. Thus secondary racks lilll -i WlllbQ reciarocated in a .ilane parallel to the upper surface olf the conveyor, and

due to the ftactzth at in the embodiment illustrated the knives d9, secured to the racks: as are positioned ina planisubstantially 111- faces ot the substance to bescut, ice Will also be divided liflllZUlltwo slices of: equal illlQlKllGSS.

it Wllll be amine-mated that by the ot a niechainsm oi? the type and a depressing lot .7 parate bioclis each of equalsize, and 1 the 5 .ze oi such a oloclt as would be cut by the blade E26 l rent the toregoing it Will be appreciated that all oi the ol'l iects of this invention have been accouuglished in that my improved type of cutting machine provides an extremely simple mechanical construction, consistent With the operations performed, and

these operations Wlll at all times be positive in character, and an operator may be enabled to handle a great amount of Work by the movement of a machine of this character. Thus the substance may be fed by any do sirable means upon the fOlWl-ltlGIlCl of the tablell and upon the conveyor consisting of theplurality of platforms. This conveyor will serve toprevent any movement of the substance with respect to the same, incident to the ripping shoes 16, associated with each plat'lorm, andthe substance Will be intermittently moved under the knife, which When the latter isot the type shown in Figures 1 to 3 ell'ects a cutting or? a single block upon each depressing o the head. The substance will be fed in the form of a plurality Of blocks to the rear end of the table, and thence by means of suitable mechanism such as the chute 30 and conveyor 31 upon the delivery table 32, whence it may be moved to any point desired. The platforms in the conveyor Will now be moved throu p311 the bath provided by the trough 83, and subjected While in this bath to the action of the out tluid, thus thoroughly cleaning all of the parts, and presenting the same in sanitary condition tor the next cycle oi operation.
